Question

What is 3x multiplied by x
(Here X is a variable)
I need my answer ASAP

Answer 1

3x multiplied by x gives you 3x²

Answer 2

Answer:

Required answer is 3x²

Step-by-step explanation:

Given,two numbers are 3x and x.

We want to find value of 3x multiplied by x.

We know, a multiplied by b

$= a \times b$

For example,

8 multiplied by 3 = 24

and 10 multiplied by 4 = 40

So,

3x multiplied by x

$= 3x \times x \\ = 3 {x}^{2}$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
